One crucial aspect of breast milk and infant formula is the presence of polyunsaturated fatty acids (PUFAs), particularly linoleic acid (LA), α-linolenic acid (ALA), and docosahexaenoic acid (DHA), which play vital roles in infant health. Our latest review, focusing on the PUFA composition of breast milk across the world, sheds light on the impact of these fatty acids on infant health, particularly in the absence or presence of DHA in infant formulas.

The levels of PUFAs in breast milk, including LA and ALA, vary depending on maternal diet and geographical location. Our review analyzed data from mothers living in 31 different countries, providing insights into the range of LA and ALA concentrations. While LA levels in breast milk have seen an increase in some regions due to dietary changes, ALA levels have remained relatively stable. Moreover, the LA/ALA ratio in breast milk has shown an upward trend, potentially affecting the bioconversion of ALA to DHA, a critical fatty acid for infant brain development.

To ensure optimal PUFA levels in infant formula, our review evaluated different LA/ALA ratios and their impact on infant health. Understanding the PUFA composition of breast milk and its implications for infant health is essential for developing high-quality infant formulas.

Our latest review highlights the importance of considering the LA/ALA ratio, DHA supplementation, and regulatory standards to ensure optimal PUFA levels in infant formulas. By aligning with the latest scientific findings and conducting further research, we can continue to enhance the nutritional value of infant formulas and contribute to the healthy development of infants worldwide.
